Chemistry class 11 saj

DAY 1 18.5.20 6 TH PERIOD Good morning Boys, Today we will be revising about methods of expressing concentration of solution. Learning Outcomes ; student will be able to Recall the formula Apply the formula Limiting Reagent: It is the reactant which  gets consumed first or limits the amount of product formed. For a balanced reaction reaction:                                     A +B →  C + D B would be a limiting reagent if n A  /n B  > n B /n A Similarly, A is a limiting reagent if n A  /n B  < n B /n A Concentration of the solutions Mass Percent: It is the mass of the solute in grams per 100 grams of the solution. Volume Percent: It is the volume of the solute  per 100 units of the volume of solution. Parts per million ...

15.5.20 DAY 5 Good Morning  Boys, Today we will learn the rules for naming elements with atomic number greater than 100. Learning Outcome: student will be able to Learn the rule Apply Rule to element with Atomic number greater than 100 1.A systematic Nomenclature is derived directly from the atomic number of the elements using the numerical roots for 0 to 9. 2.The Root word are put together inorder of digits which make up the atomic number. 3. ium is added as a suffix. The Table Below will enchance your learning on nomenclature of elements of a given atomic number. THATS ALL FOR THE DAY MARK YOUR ATTENDANCE ON THE FORM Loading…

14.5.20 Day 4 Good Morning Boys, Today you will write the experiment for the detection of Bromide and Iodide radical present in the inorganic salt. Learning Outcomes : Students will be able to Identify bromide and Iodide Radical Learn the test of acid Radical Differentiate the two radical on the basis of chemical test. Refer to the images to write the practical, related to detection of  Bromide and Iodide Radical. THATS ALL FOR THE DAY MARK YOUR ATTENDANCE ON THE FORM Loading…

DAY 3 13.5.20 Good morning Boys, Today we will start with classification of elements.  you have previuosly learned about newlands law of octaves, Mendeleevs law . Learning Outcomes : Recall classification of elements Illustrate various law for classifying elements. Dobereiner’s law of triads Dobereiner classified the elements into groups of three elements  (triads ) with similar properties in such a manner so that the atomic weight of the middle element was the arithmetic mean of the other two, e.g., Element Li NA K Atomic weight 7 23 39 Mean of atomic masses = (7 + 39) / 2 = 23 Similarly CI, Br, I; Ca, Sr, Ba are two more examples of such triads. Limitations   could not arrange all the elements known at that time into triads. He could identify only three such triads that have been mentioned. Newland’s Law of Octaves  when elements are arranged in order of increasing atomic masses the properties of eight elements are repetition o...

DAY 2 12.5.20 Good morning Boys, Today we will do the nomenclature of organic compounds by following the rules for naming an organic compound. Learning outcomes Student will be able to Apply Rules Identify Functional Group Differentiate between the different functional groups. THATS ALL FOR THE DAY MARK YOUR ATTENDANCE ON THE FORM Loading…

DAY 1 11.5.20 6th period. Good Morning Boys, Today we will revise the rules of Nomenclature of organic compounds . LEARNING OUTCOMES : Students will be able to  Identify Functional group use the rules to nomenclate the organic compound. correlate with the terms used. Rule I Longest chain rule   The chain containing the principal functional group, secondary functional group and multiple bonds as many as possible is the longest possible chain. In the absence of functional group, secondary group and multiple bonds, the chain containing the maximum number of C-atoms will be the longest possible chain. Word Root for Carbon Chain Rule 2 Lowest number rule   Numbering is done in such a way so that 1. branching if present gets the lowest number. 2. the sum of numbers of side chain is lowest. 3. principal functional group gets the lowest number. Select the principal functional group from the preference series : Functional group other than the...

DAY1 11.5.20 Good Morning Boys, Today we will discuss about functional groups Learning Outcomes : students will be able to recognize the functional group notation identify the suffix for functional group. Functional Group : An Atom or group of atoms which determines the chemical properties of compound. Loading…
